Red Lion Controls PBA04101 Module

Red Lion Controls PBA04101 Module is an Intelligent Serial Slave Module for Red Lion Large Digit Displays (LDD), identified by part number PBA04101, and designed to connect the NL-series LDD displays to a host controller via a serial link. In the Red Lion LDD ecosystem, this module functions as a serial slave interface that receives numeric data and display commands from a master device and translates them into updates on connected large-digit readouts. This makes it ideal for applications in process visualization and instrumentation where high-visibility numeric readouts are required at a remote panel or enclosure. The PBA04101 is specifically marketed as an LDD accessory with a serial connection, enabling straightforwardintegration into control architectures that rely on Red Lion display technology. Common use cases include dashboards showing measured process values, batch counts, or status indicators where quick, unambiguous numeric feedback is critical, and where the benefits of Red Lion's large-format displays are desired for operator clarity and rapid decision making.
